E5500 Phase Noise Measurement System Version A.02.00
The Ignore Out Of Lock test mode enables all of the troubleshoot
mode functions, plus it causes the software to not check for an
out-of-lock condition before or during a measurement. This allows
you to measure sources with high close-in noise that normally would
cause an out-of-lock condition and stop the measurement. When
Ignore Out Of Lock is selected, the user is responsible for monitoring
phase lock. This can be accomplished using an oscilloscope
connected to the Agilent 70420A Aux. Monitor port to verify the
absence of a beatnote and monitor the dc output level.
G
When Ignore Out Of Lock is selected, the test system does not
verify the phase lock of the measurement. The user must ensure
that the measurement maintains phase lock during the
measurement.
